property with no earth help please

[sams]

Hi,
I have been asked to price for cu change.I went around to carry pre inspection only to find that there is no earthing conductor connected to supplier side at all.
am i right assuming that there is no earth or am i missing something.
I couldnt carry ze as they both work from home and can not turrn the power off .
Please see photos attached and coment.

Thank You

If there is no earth coming in and the supplier will not supply one then might have to make it a TT installation (if that hasn't been done already, I can't see from the photos whether the MET is connected to an earthing rod). though it does say PME on the head so it might be TNCS. Personally I think you need to do a Ze test before you can do any further work.

Hi Derek
Deffenitly not conected to earthing rood.
I have two bonds going to gas and water and as you can see 16`T&e going to cu which is 8m away

 

[DurhamSparky]

remove the fuse cover and access the earthing point on the Head to check for PME!

also during the works i would remove the ELCB thats fitted also as it will be come redundant and they are crap any way!

 

[topquark]

Are you able to establish what the connections in the MET are ? There doesn't appear to be an earth from the head even though it's marked PME.

I see the seal fairy has done her bit
Elcb ? maybe not
It looks like the old MK mostly 100m/amp Rcd to my failing eyes
Dont put your money on that though

Are looking closer it is a current operated 100m/amp elcb
At least its not a voltage operated type
Its old hat and ugly so it ought to go though

 

[TPES]

Bang a rod it to cover your backside straight away. I would

yes des you are absolutly right it is ugly 300 ma elcb and it will go once I sort out earthing

You say 2 bonds yet 3 terminated in the MET. What's the third?

I think the two on the right hand side are the Gas and Water :thumbsup

Which looking at that would suggest that the Earth connection from the supplier was never made?

 

[DurhamSparky]

simples!!!

 

[1shortcircuit]

simples!!!

Meaning contact the supplier and request their urgent attendance?

Hi,
they both work from home and can not turrn the power off .

Well TELL them they could be working from home in a potentially lethal situation! TELL them you need 5-10 mins with the power off to do your Ze.

If there was a suspected gas leak would they continue tapping away at their keyboards so as not to lose work time?!

So the two on the right are Gas and water, what's the third one on the left?

From the bottom photograph it appears that 'all' that has (not) happened is that the supplier has not provided an earth from the incoming supply NEUTRAL conductor to the MET, which is what happens with a TN-C-S system? If that is the case, surely, the supplier should be contacted and asked to correct the error?

Agree with this as there is quite clearly a sign that states it's a PME and there is no earth off the header I would be calling the emergency number on the customers bill and telling the DNO exactlky what you have and get them over as soon as possible as the installation is not safe

 

[oldsalty]

Looking at it again, if the CPC lead from the ELCB to the MET is connected at the ELCB NEUTRAL connector AND the earth and neutral connections inside the ELCB are linked then, again surely (though you would have to ask why they did it this way), this serves the same purpose as connecting to the NEUTRAL conductor at the end of the supply header block? I would then run that bit of CPC into the top of the MET to make it look 'right'?

Can anyone help please, I cannot locate an earth anywhere on my property as it is made up ground! I need to get my new extension wiring signed off for my mortgage asap and what does one do when you cannot find an earth!!!

Can your electrician not locate it then???

 

[Jimmy Boy]

Lenny surely that would be the Electrician that either a) Did the work under part P and did a self cert ? or b) Notified the Local Building control and served a Building notice ?..

 

[miranda]

No, been trying for two days now, all over the garden. Cannot find solid ground. What do the 17th wiring regulations say on this point? anyone help me! ta Miranda.

 

[Jimmy Boy]

Tell us the supply characteristics and maybe we could

 

[cornburn]

I'm surprised no ones suggested getting a Zs from a nearby outlet yet if it's not easy to turn the power off. At least you'd know if it's getting an earth from anywhere then before investigating further

 

[Jimmy Boy]

Ze is a fundamental requirement for all the reasons set out in the regs Zs ? an Earth from where ? parallel paths ? Extraneous conductive parts ? That is really bad advice mate

Hi steve
Should I contact building control and ask them how to go forward if my electricain cannot locate and earth on my property??
Is it up to my supplier (eon) to sort this out?

 

[Sintra]

The supplier does not have to supply you with an earth but if they do they have to maintain it. Sounds like you need to find a suitable spot for a connection.

 

[cbw]

And an electrician who knows what he is doing!

If no earth bang a stake in somewhere and upgrade the water and gas/oil bonds

Is this a wind up ?

You have a new extension ? New when ?

No (Decent) Electrician would energise a system without establishing supply characteristics, doing a Ze/ PFC and establishing disconnection times and Earthing arrangements did you do this install yourself ?

 

[miranda]

No, this is not a wind up! today finally we have managed to locate an earth 10 ft down on our property, apparantly it was a quarry! we have a reading of 87 is that good enough?

For a TT system 87 is a good reading and well within the 200ohms stipulated in the Regs. Also as an aside it will make all the NICEIC guys on here happy as well as the NICEIC recommend that it should be lower than an 100ohms!!

 

[SimpleSimon]

Miranda and Sam are both after the same problem? Miranda are Sams photos of your property or have you hijacked the thread?
